燃气电站汽轮机组旁路系统设计

摘要

In order to improve the start-up performance of steam turbine, coordinate the balance between steam turbine and boiler and decrease steam loss in unit cycle, a set of high-low voltage 2-stage series bypass system are installed in Ge’ermu gas power station. The system has advantages of less start-up time, less loss and start-up fee and is more favorable for quick start, especially hot start.%为了改善汽轮机组的启动性能,协调机、炉间的汽量平衡,减少机组循环的汽水损失,格尔木燃气电站设置了一套高低压两级串联旁路装置,缩短了启动时间,减少了工质损失和启动费用,对机组快速启动特别是热态启动更有利。
